How Relays Work | What is a Relay? | Electromagnetic Relays Explained | Relay Logic Fundamentals

This in-depth video tutorial provides a comprehensive look at electromechanical relay fundamentals. Whether you're an engineer, electrician, or hobbyist, understanding relays is crucial for working with industrial control systems and circuits.

We'll explain the internal components and operation of relays in detail, providing clear explanations and visuals. You'll learn about the electromagnet coil, armature, spring mechanism, contacts, normally open vs normally closed configurations, pole and throw terminology, and more.

See step-by-step examples of how to wire real-world relay circuits using ladder diagrams and PLC outputs. We'll show you how to control larger loads like AC induction motors, pumps, compressors, and other equipment using low power PLC signals with relays.

An example relay motor starter circuit demonstrates how a small 24VDC programmable logic controller output can switch a much larger 120VAC three-phase motor. By acting as an electrical isolator, relays enable safe control of high power with low power signals.

You’ll gain practical knowledge for incorporating relays into your own industrial control panel designs and projects after watching this video. Understanding relay logic circuits is the foundation for learning PLC programming languages like Ladder Logic, which is based on relay wiring diagrams.

Whether you’re an electrical engineering student, electrician, industrial mechanic, manufacturing technician, or hobbyist, this video will advance your skills and knowledge for working with relays, PLCs, sensors, motors, pumps, and other electrical equipment. Boost your engineering and troubleshooting ability by learning relay fundamentals today!

The detailed explanations will help build your confidence with designing, wiring, and problem-solving real-world relay control circuits for industrial applications. Gain valuable skills to advance your career by watching now!
